It shows four digits in red, each 13 mm tall — readable at arm's length on a panel or machine fascia. The AS-Interface connection means it pulls power and data over a single two-wire bus, so you're not running separate signal cables back to the controller. Flush-mount design lets you cut a standard panel opening and drop it in with the bezel sitting flush. The AS-Interface bus handles the wiring — just daisy-chain the flat cable through the display and the gateway. It's a panel-side indicator, not a DIN-rail module, so plan for the cutout and the bus drop in your enclosure layout.","metaTitle":"Siemens 3SF4102-1B Numerical LED Display, AS-Interface, 13mm","metaDescription":"Siemens 3SF4102-1B numerical LED display for flush mounting with AS-Interface. 13mm, 4 digits, red.
